GUIDE-LUBRICATOR.

Specication of Letters Patent.

Patented April 14, 1908.

` Application led September 21, 1907. Serial No. 393,946'.

To all whom it may concern:

Be it known that I, J AMES HENRY RUSH, a

citizen of the United States, and a resident of i Boston, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Guide-Lubricators, of which the following is a full, clear, and exact description.

This invention is an improvement in guide lubricators, especially designed for elevators, and serving to automatically and effectually lubricate the guides or rails without waste, during the travel of the elevator car.

The object of the invention is to provide a receptacle for holding a lubricant, as grease or graphite, which will admit of the guide passing thereinto in contact with the lubricant, and in which the lubricant will tend to move toward the guide as it becomes exhausted.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a perspective view of a portion of the guide and cross-head of an elevator, showing one embodiment of my improvement applied thereto; Fig. 2 is a plan of the construction shown in Fig. 1; and Fig. 3 is a perspective view showing my improved luricator made as a separate part from the cross-head.

'The lubricator comprises a ho vper-shaped receptacle 5 which is preferab y substantially rectangular in cross-section, with the bottom thereof removed, and is provided with a vertical slot 6 formed-in one side for the reception of the guide or rail of the elevator, as illustrated in Figs. 1 and 2.

The side ofthe receptacle which is constructed with theslot is upright, whereas the remaining three adjacent sides are 'downwardly and inwardly inclined, whereby the grease or graphite placed in the receptacle will tend to move in the direction of the guide, as it becomes exhausted and sinks in the. receptacle.

Thewidth of the slot 6 and the open bottom of the rece tacle is such, that the rece tacle will close y fit-the rail or guide of t e elevator and thus prevent undue a plication of the grease to the guide and avoi waste.

I have shown in Fig. 1 the receptacle formed as an integral part of thel cross ead; this, however, may be modified by casting or otherwise producing the receptacle as a separate part, as illustrated in Fig. 3, and there after bolting or otherwise rigidly securing it to the cross-head. For this purpose, as shown in Fig. 3, the receptacle is provided at its bottom with an exteriorly arranged flange 7, the said flange surrounding the receptac e exce t at the slotted side thereof.

ile the design of my improved lubricator as shown and described is my preferred practical construction, it is obvious that minor changes may be resorted to without departing from the nature of my invention as defined in the annexed claims.

Having thus described -.my invention, I claim as new and desire to secure by Letters Patent:

1. 4A guide lubricator comprising a hoppershaped receptacle for holding the lubrlcant, having a slot in one side thereof for receiving the guide of the elevator, whereby said guide asses into the receptacle in contact with the ubricant. v

2. A guide lubricator comprising a rece tacle for holding the lubricant, having t e bottom thereof open and provided with a vertical slotted side for receiving and substantially iitting the guide, whereby said guide is adapted to roject into the receptacle in contact with t e lubricant.

3. A guide lubricator comprising a receptacle of substantially rectangular cross-section for holding the lubricant, having the bottom thereof open and with three adjacent sides inclining inwardly and downwardly, the other side of the receptacle beingsubstantially vertically slotted for permitting said guide to project within the receptacle in contact with the lubricant.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JAMES HENRY RUSH.
